A Correct answer
Explanation

Use the formula (M1*D1*H1)/W1 = (M2*D2*H2)/W2. (10*12*8)/725 = (4*16*9)/W2. 960/725 = 576/W2. W2 = (576 * 725) / 960 = 435.

AI explanation

Using the formula (P1 x D1 x H1) / W1 = (P2 x D2 x H2) / W2, we substitute the values: (10 x 12 x 8) / 725 = (4 x 16 x 9) / W2. Cross-multiplying gives W2 x 960 = 576 x 725. Solving this yields W2 = 435 paintings.
